TECHNICAL FIELD

This disclosure relates to automated robot systems and, more particularly, to automated robot systems for use within the building trades and the construction industry.

BACKGROUND

The robotics industry is enabling the automation of tedious and/or repetitive tasks. Numerous industries (such as the consumer electronics industry and the automotive industry) make extensive use of robotics. And through the use of robotics, a higher level of worker safety may be realized (as robots may be utilized in dangerous environments). Further, a higher level of predictability may be achieved, as robots may continuously and repeatedly perform that same task with a high level of consistency.

Unfortunately, certain industries have been slower to adopt robotic technology. For example, the building trades and the construction industry have been slower to utilizes such technology due to the mobility requirements of the robots and the transient nature of the job locations.

As is known in the art, Bluetooth is a telecommunications industry specification that allows e.g., mobile phones, computers, and personal digital assistants to be interconnected using a short-range wireless connection.

Concept 1 (Automated Application)

As discussed above, automated construction robot system 10 may include computational system 32 configured to execute automated construction robot process 34 and enable the interfacing with (and controlling of) one or more of mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26.

Accordingly and referring also to FIG. 2, automated construction robot process 34 may be configured to manipulate 100 one or more of mobile base assembly 12, head assembly 16 and arm assembly 20 to apply coating material 48 (e.g., a sealer coating, a primer coating, a paint coating, a stain coating, a varnish coating, a polyurethane coating, and an epoxy-based coating) to work surface 18 via head assembly 16.

Coating material 48 may be locally or remotely provided. For example, automated construction robot system 10 may include an internal chamber (e.g., internal chamber 50) within which coating material 48 may be stored. For example, internal chamber 50 may be configured so that user 42 of automated construction robot system 10 may fill internal chamber 50 with coating material 48 from e.g., a supply bucket/container. Alternatively, automated construction robot system 10 may be configured to receive coating material 48 from an external container. For example, supply line assembly 52 may be configured to be coupled to external container 54 (that may contain coating material 48). Additional external containers (e.g., flushing fluid supply container 56 and flushing fluid receipt container 58) may be utilized by automated construction robot system 10 to effectuate the cleaning of the same (wherein supply line assembly 52 may be placed into flushing fluid supply container 56 and head assembly 16 may be positioned to discharge into flushing fluid receipt container 58).

When manipulating 100 one or more of mobile base assembly 12, head assembly 16 and arm assembly 20 to apply coating material 48 to work surface 18 via head assembly 16, automated construction robot process 34 perform one or more of the following operations:

-   -   Controlling 102 the movement of mobile base assembly 12 within         work area 14. For example, automated construction robot process         34 may be configured to control 102 the movement of mobile base         assembly 12 in the X-axis (perpendicular to work surface 18)         and/or Y-axis (parallel to work surface 18). Specifically,         automated construction robot process 34 may be configured to         repeatedly move mobile base assembly 12 along the Y-axis to         allow for the continued application of coating material 48 to         work surface 18.     -   Extending/retracting 104 arm assembly 20 with respect to mobile         base assembly 12. For example, automated construction robot         process 34 may be configured to extend/retract 104 arm assembly         20, resulting in the displacement of head assembly 16 in the         X-axis, Y-axis and/or Z-axis and the positioning of head         assembly 16 with respect to work surface 18.     -   Controlling 106 the location of head assembly 16 with respect to         work surface 18 and/or mobile base assembly 12. For example,         automated construction robot process 34 may be configured to         control arm assembly 20, wrist assembly 22 and/or rotation         assembly 24 to control 106 the location of head assembly 16 with         respect to work surface 18 and/or mobile base assembly 12.         Specially, automated construction robot process 34 may control         106 the location of head assembly 16 to e.g., move head assembly         16 along the Z-axis and apply coating material 48 in vertical         stripes along work surface 18. Further, automated construction         robot process 34 may control 106 the location of head assembly         16 to e.g., move head assembly 16 along the Y-axis and apply         coating material 48 in horizontal stripes along work surface 18.         Additionally, automated construction robot process 34 may         control 106 the location of head assembly 16 to e.g., move head         assembly 16 along the X-axis (i.e., toward and away from work         surface 18) to vary the width of the stripe of coating material         48 applied to work surface 18.     -   Controlling 108 the velocity of head assembly 16 with respect to         work surface 18 and/or mobile base assembly 12. For example,         automated construction robot process 34 may be configured to         control the rate at which arm assembly 20 moves, control the         rate at which wrist assembly 22 moves and/or control the rate at         which rotation assembly 24 moves to control 108 the velocity of         head assembly 16 with respect to work surface 18 and/or mobile         base assembly 12. Specifically, by controlling 108 the velocity         of head assembly 16 (with respect to work surface 18), the         thickness of coating material 48 applied to work surface 18 may         be regulated.     -   Rotating 110 head assembly 16 with respect to work surface 18.         For example, automated construction robot process 34 may be         configured to control wrist assembly 22, thus enabling the         rotation of head assembly 16 about an X-axis, a Y-axis, and/or a         Z-axis. For example, if head assembly 16 is positioned to         generate a horizontal spray fan (as shown in FIGS. 1A-1B) when         applying coating material 48, head assembly 16 may be displaced         in the Z-axis to generate a vertical stripe of coating material         48. Alternatively, automated construction robot process 34 may         rotate 110 head assembly 16 ninety degrees about the X-axis,         thus positioning head assembly 16 to generate a vertical spray         fan (not shown) when applying coating material 48, thus allowing         head assembly 16 to be displaced in the Y-axis to generate a         horizontal stripe of coating material 48.     -   Controlling 112 the angle of incidence (θ) of head assembly 16         with respect to work surface 18. Referring also to FIG. 3, the         angle of incidence (θ) is the angle between a ray incident on a         surface (e.g., work surface 18) and the line perpendicular to         the surface at the point of incidence. Accordingly and when         spray fan 150 is positioned perpendicular to work surface 18 (as         shown in solid lines), the angle of incidence (θ) is 90 degrees.         This may result in a decrease in the crispness of the edges 152,         154 of coating material 48 applied to work surface 18. However,         rotating spray fan 150 about pivot point 156 included within         wrist assembly 22 in a clockwise/counterclockwise direction may         result in a decrease in the angle of incidence (θ) and an         increase in the crispness of: the edge 152 (when rotating in a         clockwise direction); and edge 154 (when rotating in a         counterclockwise direction).     -   Controlling 114 a spray fan width (e.g., spray fan width 158) of         coating material 48 applied to work surface 18 via head assembly         16. For example, nozzle assembly 160 of head assembly 16 may be         a variable geometry nozzle assembly that is configurable to         allow for adjustment of spray fan width 158 (thus allowing for         the increase/decrease of spray fan width 158).     -   Controlling 116 the volume of coating material 48 provided to         head assembly 16. For example, supply line assembly 52 may be         utilized to receive coating material 48 from a coating supply         system (e.g., internal chamber 50 or external container 54).         Pump assembly 162 may be utilized to pressurize coating material         48 (drawn from internal chamber 50/external container 54) and         variable-duty-cycle microcontroller assembly 164 may be utilized         to control 116 the volume of coating material 48 provided to         head assembly 16, wherein pump assembly 162 and/or         variable-duty-cycle microcontroller assembly 164 may be         controllable by automated construction robot process 34 (as will         be discussed below in greater detail).     -   Controlling 118 the pressure of coating material 48 provided to         head assembly 16. For example, supply line assembly 52 may be         utilized to receive coating material 48 from a coating supply         system (e.g., internal chamber 50 or external container 54).         Pump assembly 162 may be utilized to pressurize coating material         48 (drawn from internal chamber 50/external container 54) and         variable-duty-cycle microcontroller assembly 164 may be utilized         to control 118 the pressure of coating material 48 provided to         head assembly 16, wherein pump assembly 162 and/or         variable-duty-cycle microcontroller assembly 164 may be         controllable by automated construction robot process 34 (as will         be discussed below in greater detail).

Concept 2 (Generation of a Coating Plan)

As discussed above, automated construction robot system 10 may include computational system 32 configured to execute automated construction robot process 34 and enable the interfacing with (and controlling of) one or more of mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26.

Further and as discussed above, automated construction robot system 10 may include machine vision system 26 configured to scan a target area (e.g., target area 28) and generate target area information 30. When scanning target area 28 to generate target area information 30, automated construction robot process 34 may manipulate and maneuver automated construction robot system 10 (generally) and mobile base assembly 12 (specifically) so that machine vision system 26 may scan the entirety of work surface 18 to generate target area information 30.

Referring also to FIG. 4, automated construction robot process 34 may be configured to process 200 target area information 30 to define work area coating plan 60. For this example, assume that work surface 18 is a room that includes four walls, two doors, two windows, six electrical outlets and two light switches. Accordingly, automated construction robot process 34 may process 200 target area information 30 to locate such walls, doors, windows, electrical outlets and light switches within work surface 18 and define work area coating plan 60.

Once work area coating plan 60 is defined, automated construction robot process 34 may generate 202 one or more coating plan instructions (e.g., coating plan instructions 62) based, at least in part, upon work area coating plan 60. Generally, coating plan instructions 62 may instruct the various portions of automated construction robot system 10 (e.g., mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26) to apply coating material 48 to whatever portions of work surface 18 need to be coated (e.g. bare drywall) while bot applying coating material 48 to whatever portions of work surface 18 should not be coated (e.g. doors, windows, electrical outlets, light switches). For example, if the first wall within work surface 18 is 10′ high and 50′ long (with a 4′ wide by 7′ high door located in the center of that first wall), the coating plan instructions (e.g., coating plan instructions 62) generated 202 may instruct the various portions of automated construction robot system 10 (e.g., mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26) to e.g., applying coating material 48 from the floor to a height of 10′ for the first 23′ of the first wall . . . and then apply coating material 48 from 8′ to 10′ for the next 4′ of the first wall . . . and then apply coating material 48 from the floor to a height of 10′ for the remaining 23′ of the first wall.

Once coating plan instructions 62 are generated 202, automated construction robot process 34 may manipulate 204 one or more of mobile base assembly 12, head assembly 16 and arm assembly 20 to apply coating material 48 to work surface 18 via head assembly 12 based, at least in part, upon one or more the coating plan instructions (e.g., coating plan instructions 62). For example, assume that head assembly 12 applies coating material 48 in e.g., a 12″ wide stripe. Accordingly, automated construction robot process 34 may manipulate 204 the various portions of automated construction robot system 10 (e.g., mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26) to apply twenty-three 12″ wide vertical stripes of coating material 48 from floor level to 10′ high . . . and then apply four 12″ wide vertical stripes of coating material 48 from 8′ feet high to 10′ feet high . . . and then apply twenty-three 12″ wide vertical stripes of coating material 48 from floor level to 10′ high.

Depending upon how automated construction robot process 34 is configured, automated construction robot process 34 may overlap these stripes of coating material 48 to ensure consistent coverage.

Concept 3 (Automated Repair)

As discussed above, automated construction robot system 10 may include computational system 32 configured to execute automated construction robot process 34 and enable the interfacing with (and controlling of) one or more of mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26.

Further and as discussed above, automated construction robot system 10 may include machine vision system 26 configured to scan a target area (e.g., target area 28) and generate target area information 30. When scanning target area 28 to generate target area information 30, automated construction robot process 34 may manipulate and maneuver automated construction robot system 10 (generally) and mobile base assembly 12 (specifically) so that machine vision system 26 may scan the entirety of work surface 18 to generate target area information 30.

Referring also to FIG. 5, automated construction robot process 34 may be configured to process 250 target area information 30 to identify any surface defects (e.g., surface defect 64). As is known, when drywall is installed, the seams and interior corners are covered with a combination of joint tape and drywall compound. And the fasteners that attach the drywall to the underlying studs are fastened via drywall screws and/or drywall nails, wherein the heads of such fasteners are also covered with drywall compound. Further, exterior corners are covered with corner bead that is fastened with either drywall screws or drywall nails, wherein this corner bead and these fasteners are covered with drywall compound.

And while all surface defects are supposed to be addressed during the finishing of the drywall, surface defects are routinely missed and need to be addressed prior to the application of coating material 48. Evidence of such surface defects (e.g., surface defect 64) may be memorialized (e.g., via stored images and/or videos) to document such surface defects and provide evidence of the same for reimbursement purposes from third parties (e.g., the drywall installers).

Examples of such surface defects (e.g., surface defect 64) may include but are not limited to one or more of:

-   -   A High Spot within the Work Surface 18: For example, a portion         of drywall compound that was applied to work surface 18 may have         been insufficiently sanded, resulting in a high spot within work         surface 18 that needs to be repaired.     -   A Low Spot within Work Surface 18: For example, an insufficient         quantity of drywall compound may have been applied to work         surface 18, resulting in a depression within work surface 18         that needs to be repaired.     -   A Crack within Work Surface 18: For example, a joint within the         drywall, or an interior/exterior corner may be been         insufficiently taped, resulting in a crack within work surface         18 that needs to be repaired.     -   A Hole within Work Surface 18: For example, damage to a piece of         drywall may have occurred, resulting in a hole within work         surface 18 that needs to be repaired.     -   A Protruding Screw within Work Surface 18: For example, a         drywall screw may have been insufficiently set within work         surface 18, resulting in a protruding screw head within work         surface 18 that needs to be repaired.     -   A Protruding Nail within Work Surface 18: For example, a drywall         nail may have been insufficiently set within work surface 18,         resulting in a protruding nail head within work surface 18 that         needs to be repaired.

Once a surface defect (e.g., surface defect 64) is identified, automated construction robot process 34 may generate 252 one or more remedial instructions (e.g., remedial instructions 66) based, at least in part, upon the surface defect (e.g., surface defect 64) identified. As would be expected, these remedial instructions (e.g., remedial instructions 66) may vary depending upon the type of surface defect (e.g., surface defect 64) identified.

Accordingly:

-   -   A High Spot within the Work Surface 18: For such a surface         defect, the remedial instructions (e.g., remedial instructions         66) generated 252 by automated construction robot process 34 may         include:         -   i. the sanding of work surface 18 to make the surface flat.     -   A Low Spot within Work Surface 18: For such a surface defect,         the remedial instructions (e.g., remedial instructions 66)         generated 252 by automated construction robot process 34 may         include:         -   i. the application of drywall compound to work surface 18 to             fill the depression; and         -   ii. the sanding of work surface 18 to make the surface flat.     -   A Crack within Work Surface 18: For such a surface defect, the         remedial instructions (e.g., remedial instructions 66) generated         252 by automated construction robot process 34 may include:         -   i. the application of drywall compound to work surface 18 to             fill the crack; and         -   ii. the sanding of work surface 18 to make the surface flat.     -   A Hole within Work Surface 18: For such a surface defect, the         remedial instructions (e.g., remedial instructions 66) generated         252 by automated construction robot process 34 may include:         -   i. the application of drywall compound to work surface 18 to             fill the hole; and         -   ii. the sanding of work surface 18 to make the surface flat.     -   A Protruding Screw within Work Surface 18: For such a surface         defect, the remedial instructions (e.g., remedial instructions         66) generated 252 by automated construction robot process 34 may         include:         -   i. the setting of the protruding screw;         -   ii. the application of drywall compound to work surface 18             to cover the screw head; and         -   iii. the sanding of work surface 18 to make the surface             flat.     -   A Protruding Nail within Work Surface 18: For such a surface         defect, the remedial instructions (e.g., remedial instructions         66) generated 252 by automated construction robot process 34 may         include:         -   i. the setting of the protruding nail;         -   ii. the application of drywall compound to work surface 18             to cover the nail head; and         -   iii. the sanding of work surface 18 to make the surface             flat.

Once the remedial instructions (e.g., remedial instructions 66) are generated 252, automated construction robot process 34 may manipulate 254 one or more of mobile base assembly 12, head assembly 16 and arm assembly 22 based, at least in part, upon the one or more remedial instructions (e.g., remedial instructions 66). Generally, remedial instructions 66 may instruct the various portions of automated construction robot system 10 (e.g., mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26) to perform the above-described remedial actions. For example, manipulating 254 one or more of mobile base assembly 12, head assembly 16 and arm assembly 22 based, at least in part, upon the one or more remedial instructions (e.g., remedial instructions 66) may include one or more of:

-   -   Utilizing 256 head assembly 12 to sand the surface defect (e.g.,         surface defect 64) identified. For example, if head assembly 16         is configured to sand the surface defect (e.g., surface defect         64) included within work surface 18, head assembly 16 may be         utilized to perform such sanding functionality. In the event         that head assembly 16 affixed to arm assembly 20 is not capable         of sanding the surface defect (e.g., surface defect 64)         identified, a head assembly capable of performing such sanding         functionality may be selected by arm assembly 20 from plurality         of head assemblies 68.     -   Utilizing 258 head assembly 12 to apply joint compound to the         surface defect (e.g., surface defect 64) identified. For         example, if head assembly 16 is configured to apply joint         compound to the surface defect (e.g., surface defect 64)         included within work surface 18, head assembly 16 may be         utilized to perform such joint compound application         functionality. In the event that head assembly 16 affixed to arm         assembly 20 is not capable of applying joint compound to the         surface defect (e.g., surface defect 64) identified, a head         assembly capable of performing such joint compound application         functionality may be selected by arm assembly 20 from plurality         of head assemblies 68.     -   Utilizing 260 head assembly 12 to apply joint tape to the         surface defect (e.g., surface defect 64) identified. For         example, if head assembly 16 is configured to apply joint tape         to the surface defect (e.g., surface defect 64) included within         work surface 18, head assembly 16 may be utilized to perform         such joint tape application functionality. In the event that         head assembly 16 affixed to arm assembly 20 is not capable of         applying joint tape to the surface defect (e.g., surface defect         64) identified, a head assembly capable of performing such joint         tape application functionality may be selected by arm assembly         20 from plurality of head assemblies 68.     -   Utilizing 262 head assembly 12 to set a protruding drywall screw         within the surface defect (e.g., surface defect 64) identified.         For example, if head assembly 16 is configured to set the         protruding screw (e.g., surface defect 64) included within work         surface 18, head assembly 16 may be utilized to perform such         screw setting functionality. In the event that head assembly 16         affixed to arm assembly 20 is not capable of setting the         protruding screw (e.g., surface defect 64), a head assembly         capable of performing such screw setting functionality may be         selected by arm assembly 20 from plurality of head assemblies         68.     -   Utilizing 264 head assembly 12 to set a protruding nail within         the surface defect (e.g., surface defect 64) identified. For         example, if head assembly 16 is configured to set the protruding         nail (e.g., surface defect 64) included within work surface 18,         head assembly 16 may be utilized to perform such nail setting         functionality. In the event that head assembly 16 affixed to arm         assembly 20 is not capable of setting the protruding nail (e.g.,         surface defect 64), a head assembly capable of performing such         nail setting functionality may be selected by arm assembly 20         from plurality of head assemblies 68.

Concept 4 (Contact Detection)

As discussed above, automated construction robot system 10 may include computational system 32 configured to execute automated construction robot process 34 and enable the interfacing with (and controlling of) one or more of mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26.

As discussed above, when scanning target area 28 to generate target area information 30, automated construction robot process 34 may manipulate and maneuver automated construction robot system 10 (generally) and mobile base assembly 12 (specifically) so that machine vision system 26 may scan the entirety of work surface 18 to generate target area information 30. Additionally and as discussed above, automated construction robot process 34 may manipulate 100 one or more of mobile base assembly 12, head assembly 16 and arm assembly 20 to apply coating material 48 to work surface 18 via head assembly 16. Further and as discussed above, automated construction robot process 34 may manipulate 204 one or more of mobile base assembly 12, head assembly 16 and arm assembly 20 to apply coating material 48 to work surface 18 via head assembly 12 based, at least in part, upon one or more the coating plan instructions (e.g., coating plan instructions 62). Additionally and as discussed above, automated construction robot process 34 may manipulate 254 one or more of mobile base assembly 12, head assembly 16 and arm assembly 22 based, at least in part, upon the one or more remedial instructions (e.g., remedial instructions 66). Accordingly, it is foreseeable that one or more of mobile base assembly 12, head assembly 16 and arm assembly 22 may make contact with (or impact) another object, examples of which may include but are not limited to a worker, a wall, and a piece of furniture.

Referring also to FIG. 6, when automated construction robot process 34 is manipulating 300 (for any of the reasons discussed above) one or more of mobile base assembly 12, head assembly 66 and arm assembly 22, if contact of mobile base assembly 12, head assembly 16 and/or arm assembly 22 with an object (e.g., user 42) is detected 302, automated construction robot process 34 may adjust 304 the manipulation of mobile base assembly 12, head assembly 16 and/or arm assembly 22 in response to sensing such contact with the object (e.g., user 42).

As discussed above, examples of arm assembly 20 may include any hydraulically-actuated, pneumatically-actuated, and/or electrically-actuated computer-controllable arm assembly that may be configured to movably-couple head assembly 16 and mobile base assembly 12. Accordingly, automated construction robot process 34 may be configured to monitor the hydraulic and/or pneumatic pressures within arm assembly 20 (to detect 302 such a contact event). If electrically actuated, automated construction robot process 34 may be configured to monitor the electrical current within arm assembly 20 (to detect 302 such a contact event). Additionally, touch sensitive bumper assemblies (e.g., bumper assembly 68) may be included within base assembly 12 and configured to detect 302 such a contact event.

When adjusting 304 the manipulation of mobile base assembly 12, head assembly 16 and/or arm assembly 22 in response to sensing such contact with the object (e.g., user 42), automated construction robot process 34 may effectuate one or more of the following operations:

-   -   Ceasing 306 movement of mobile base assembly 12, head assembly         16 and/or arm assembly 22 upon sensing such contact with the         object (e.g., user 42). For example and upon detecting 302 such         a contact event, automated construction robot process 34 may         immediately cease 306 any and all movement of mobile base         assembly 12, head assembly 16 and/or arm assembly 22.     -   Reversing 308 movement of mobile base assembly 12, head assembly         16 and/or arm assembly 22 upon sensing such contact with the         object (e.g., user 42). For example and upon detecting 302 such         a contact event, automated construction robot process 34 may         immediately reverse 308 any and all movement of mobile base         assembly 12, head assembly 16 and/or arm assembly 22.

Concept 6 (Edge Detection & Instruction)

As discussed above, automated construction robot system 10 may include computational system 32 configured to execute automated construction robot process 34 and enable the interfacing with (and controlling of) one or more of mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26.

Further and as discussed above, automated construction robot system 10 may include machine vision system 26 configured to scan a target area (e.g., target area 28) and generate target area information 30. When scanning target area 28 to generate target area information 30, automated construction robot process 34 may manipulate and maneuver automated construction robot system 10 (generally) and mobile base assembly 12 (specifically) so that machine vision system 26 may scan the entirety of work surface 18 to generate target area information 30. As discussed above and for this example, assume that work surface 18 is a room that includes four walls, two doors, two windows, six electrical outlets and two light switches.

Referring also to FIG. 7 and as discussed above, automated construction robot process 34 may be configured to manipulate 100 one or more of mobile base assembly 12, head assembly 16 and arm assembly 20 to apply coating material 48 to work surface 18 via head assembly 16. As discussed above, automated construction robot process 34 may process 200 target area information 30 to locate e.g., walls, doors, windows, electrical outlets and light switches within work surface 18.

Accordingly, automated construction robot process 34 may process 350 target area information 30 to generate one or more edge instructions (e.g., edge instructions 70). When processing 350 target area information 30 to generate one or more edge instructions (e.g., edge instructions 70), automated construction robot system 10 may effectuate the following operations:

-   -   Identifying 352 an object within target area information 30 to         be avoided. For example, automated construction robot process 34         may process 350 target area information 30 to identify 352         objects (e.g., walls, doors, windows, electrical outlets and         light switches) to be avoided within work surface 18.     -   Processing 354 target area information 30 to generate one or         more edge instructions (e.g., edge instructions 70) for applying         coating material 48 to work surface 18 while avoiding the         identified object (e.g., walls, doors, windows, electrical         outlets and light switches) within work surface 18.

Automated construction robot process 34 may manipulate 356 the angle of incidence of head assembly 16 with respect to work surface 18 based, at least in part, upon the one or more edge instructions (e.g., edge instructions 70). As discussed above and referring again to FIG. 3, the angle of incidence (θ) is the angle between a ray incident on a surface (e.g., work surface 18) and the line perpendicular to the surface at the point of incidence. Accordingly and when spray fan 150 is positioned perpendicular to work surface 18 (as shown in solid lines), the angle of incidence (θ) is 90 degrees. This may result in a decrease in the crispness of edges 152, 154 of coating material 48 applied to work surface 18 (thus allowing for the dithering of edges 152, 154 and a blending of the stripes of coating material 48). However, rotating spray fan 150 about pivot point 156 included within wrist assembly 22 in a clockwise/counterclockwise direction may result in a decrease in the angle of incidence (θ) and an increase in the crispness of: the edge 152 (when rotating in a clockwise direction) and edge 154 (when rotating in a counterclockwise direction); thus allowing for coating material 48 to be “cut in” around e.g., ceilings, floors, walls, doors, windows, switches, outlets, baseboard moldings, crown moldings, etc.

Accordingly and when manipulating 356 the angle of incidence (θ) of head assembly 16 with respect to work surface 18 based, at least in part, upon the one or more edge instructions (e.g., edge instructions 70), automated construction robot process 34 effectuate one or more of the following operations:

-   -   Rotating 358 head assembly 16 about an X-axis, which would         enable automated construction robot process 34 to e.g., switch         spray fan 150 between a horizontal orientation and a vertical         orientation.     -   Rotating 360 head assembly 16 about a Y-axis, which would enable         automated construction robot process 34 to e.g., adjust the         crispness of edges 152, 154 of coating material 48 applied to         work surface 18 when spray fan 150 is vertically orientated.     -   Rotating 362 head assembly 16 about a Z-axis, which would enable         automated construction robot process 34 to e.g., adjust the         crispness of edges 152, 154 of coating material 48 applied to         work surface 18 when spray fan 150 is horizontally orientated.

Therefore and when manipulating 356 the angle of incidence (θ) of head assembly 16 with respect to work surface 18 based, at least in part, upon the one or more edge instructions (e.g., edge instructions 70), automated construction robot process 34 may effectuate one or more of the following operations:

-   -   decreasing 364 the angle of incidence (θ) to increase the         crispness of an edge (e.g., edges 152 and/or edge 154) of         coating material 48 applied to work surface 18 (in the manner         described above).     -   increasing 366 the angle of incidence (θ) to decrease the         crispness of an edge (e.g., edges 152 and/or edge 154) of         coating material 48 applied to work surface 18 (in the manner         described above).

Concept 7 (Non-Target Area Scanning)

As discussed above, automated construction robot system 10 may include computational system 32 configured to execute automated construction robot process 34 and enable the interfacing with (and controlling of) one or more of mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26.

Further and as discussed above, automated construction robot system 10 may include machine vision system 26 configured to scan a target area (e.g., target area 28) and generate target area information 30. When scanning target area 28 to generate target area information 30, automated construction robot process 34 may manipulate and maneuver automated construction robot system 10 (generally) and mobile base assembly 12 (specifically) so that machine vision system 26 may scan the entirety of work surface 18 to generate target area information 30.

Additionally, machine vision system 26 may be configured to scan a non-target area (e.g., non-target area 72 and/or non-target area 74) and generate non-target area information 76. These non-target areas (e.g., non-target area 72 and/or non-target area 74) may be positioned proximate target area 28. For example, non-target area 72 may be positioned on the left of target area 28 and/or non-target area 74 may be positioned on the right of target area 28. Accordingly and assuming that coating material 48 is applied in a left-to-right fashion, non-target area 72 may be the area to which coating material 48 has already been applied and non-target area 74 may be the area to which coating material 48 has not yet been applied.

Referring also to FIG. 8 and as discussed above, automated construction robot process 34 may be configured to manipulate 100 one or more of mobile base assembly 12, head assembly 16 and arm assembly 20 to apply coating material 48 to work surface 18 via head assembly 16. Additionally, automated construction robot process 34 may be configured to process 400 the non-target area information (e.g., non-target area information 76) to generate one or more remedial instructions (e.g., remedial instructions 66).

Further and as discussed above, automated construction robot process 34 may manipulate 402 one or more of mobile base assembly 12, head assembly 16 and arm assembly 22 based, at least in part, upon the one or more remedial instructions (e.g., remedial instructions 66). Generally, remedial instructions 66 may instruct the various portions of automated construction robot system 10 (e.g., mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26) to perform various remedial actions (as will be discussed below in greater detail).

As discussed above, non-target area 72 may include an area (within work surface 18) to which coating material 48 has already been applied, wherein processing 400 non-target area information 76 to generate one or more remedial instructions (e.g., remedial instructions 66) includes processing 404 non-target area information 76 to identify an applied coating material defect (e.g., coating defect 80) within non-target area 72.

Examples of such applied coating material defects (e.g., coating defect 80) may include but are not limited to one or more of:

-   -   No Coverage: An area to which coating material 48 was not         applied at all (resulting in bare drywall),     -   Light Coverage: An area to which coating material 48 was applied         too thinly (resulting in partially bare drywall).     -   Heavy Coverage: An area to which coating material 48 was applied         too heavily (which may have resulted in a run or a sag).

When manipulating 402 one or more of mobile base assembly 12, head assembly 16 and arm assembly 22 based, at least in part, upon the one or more remedial instructions (e.g., remedial instructions 66), automated construction robot process 34 may manipulate 406 one or more of mobile base assembly 12, head assembly 16 and arm assembly 22 to address the identified applied coating material defect (e.g., coating defect 80).

Examples of the manner in which automated construction robot process 34 may manipulate 406 one or more of mobile base assembly 12, head assembly 16 and arm assembly 22 to address the identified applied coating material defect (e.g., coating defect 80) may include but are not limited to:.

-   -   Utilizing head assembly 16 to apply coating material 48 to the         area to which coating material 48 was not applied at all.     -   Utilizing head assembly 16 to apply coating material 48 to the         area to which coating material 48 was applied too thinly.     -   Utilizing head assembly 16 to sand the run/sag and to apply         coating material 48 to the area that was sanded to address the         run/sag.

As discussed above, non-target area 74 may include an area (within work area 18) to which coating material 48 has not yet been applied, wherein processing 400 non-target area information 76 to generate one or more remedial instructions (e.g., remedial instructions 66) may include processing 408 non-target area information 76 to identify a surface defect (e.g., surface defect 64) within non-target area 74.

As discussed above, examples of such surface defects (e.g., surface defect 64) may include but are not limited to one or more of:

-   -   A High Spot within the Work Surface 18: For example, a portion         of drywall compound that was applied to work surface 18 may have         been insufficiently sander, resulting in a high spot within work         surface 18 that needs to be repaired.     -   A Low Spot within Work Surface 18: For example, an insufficient         quantity of drywall compound may have been applied to work         surface 18, resulting in a depression within work surface 18         that needs to be repaired.     -   A Crack within Work Surface 18: For example, a joint within the         drywall, or an interior/exterior corner may be been         insufficiently taped, resulting in a crack within work surface         18 that needs to be repaired.     -   A Hole within Work Surface 18: For example, damage to a piece of         drywall may have occurred, resulting in a hole within work         surface 18 that needs to be repaired.     -   A Protruding Screw within Work Surface 18: For example, a         drywall screw may have been insufficiently set within work         surface 18, resulting in a protruding screw head within work         surface 18 that needs to be repaired.     -   A Protruding Nail within Work Surface 18: For example, a drywall         nail may have been insufficiently set within work surface 18,         resulting in a protruding nail head within work surface 18 that         needs to be repaired.

When manipulating 402 one or more of mobile base assembly 12, head assembly 16 and arm assembly 22 based, at least in part, upon the one or more remedial instructions (e.g., remedial instructions 66), automated construction robot process 34 may manipulate 410 one or more of mobile base assembly 12, head assembly 16 and arm assembly 22 to address the identified surface defect (e.g., surface defect 64).

Examples of the manner in which automated construction robot process 34 may manipulate 410 one or more of mobile base assembly 12, head assembly 16 and arm assembly 22 to address the identified surface defect (e.g., surface defect 64) may include but are not limited to:.

-   -   Utilizing head assembly 16 to sand the surface defect (e.g.,         surface defect 64) identified.     -   Utilizing head assembly 16 to apply joint compound to the         surface defect (e.g., surface defect 64) identified.     -   Utilizing head assembly 16 to apply joint tape to the surface         defect (e.g., surface defect 64) identified.     -   Utilizing head assembly 16 to set a protruding drywall screw         within the surface defect (e.g., surface defect 64) identified.     -   Utilizing head assembly 16 to set a protruding nail within the         surface defect (e.g., surface defect 64) identified.

Concept 5 (Variable Duty Cycle Microcontroller)

As discussed above, automated construction robot system 10 may include computational system 32 configured to execute automated construction robot process 34 and enable the interfacing with (and controlling of) one or more of mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26. Further and as discussed above, automated construction robot process 34 may be configured to manipulate 100 one or more of mobile base assembly 12, head assembly 16 and arm assembly 20 to apply coating material 48 to work surface 18 via head assembly 16.

Referring also to FIG. 9 and as discussed above, supply line assembly 52 may be utilized to receive coating material 48 from a coating supply system (e.g., internal chamber 50 or external container 54). Pump assembly 162 may be utilized to pressurize coating material 48 (drawn from internal chamber 50/external container 54) and variable-duty-cycle microcontroller assembly 164 may be utilized to control 116 the volume of coating material 48 and/or control 118 the pressure of coating material 48 provided to head assembly 16.

Variable-duty-cycle microcontroller 164 may include:

-   -   inlet port 450 configured to receive coating material 48 from         the coating supply system. Examples of such a coating supply         system may include an internal chamber (e.g., internal chamber         50) within which coating material 48 may be stored and/or an         external container (e.g., external container 54) that may         contain coating material 48. This coating supply system may be a         pressurized coating supply system (e.g., it may include pump         assembly 162) in order to provide coating material 48 to inlet         port 450 of variable-duty-cycle microcontroller 164.     -   outlet port 452 configured to provide a regulated quantity of         coating material 48 to head assembly 16.     -   coating material regulation system 454 configured to control the         passage of coating material 48 from inlet port 450 to outlet         port 452, wherein coating material regulation system 454 may be         configured to process a variable-duty-cycle control signal         (e.g., control signal 456) provided by computational system 32         and regulate the quantity of coating material 48 applied to work         surface 18 via head assembly 16. As will be discussed below in         greater detail, the variable duty cycle control signal (e.g.,         control signal 456) may be is configured to have an increased         duty cycle (e.g., control signal 456A) when an increased         quantity of coating material 48 is needed at outlet port 452.         Conversely, the variable duty cycle control signal (e.g.,         control signal 456) may be configured to have a decreased duty         cycle (e.g., control signal 456B) when a decreased quantity of         coating material 48 is needed at outlet port 452.

Coating material regulation system 454 may include one or more valve assemblies (e.g., valve assemblies 458) configured to selectively fluidly-couple inlet port 450 and outlet port 452. The one or more valve assemblies (e.g., valve assemblies 458) may be configured to be selectively energized and deenergized based, at least in part, upon the variable-duty-cycle control signal (e.g., control signal 456). For example, automated construction robot process 34 may be configured to monitor the pressure of coating material 48 being applied to head assembly 16.

In the event that the pressure of coating material 48 being applied to head assembly 16 is too high, the variable-duty-cycle control signal (e.g., control signal 456) may be adjusted to regulate the pressure of the coating material 48 being applied to head assembly 16 downward. For example, the variable duty cycle control signal (e.g., control signal 456) may be adjusted to have a decreased duty cycle (e.g., control signal 506B) when a decreased quantity of coating material 48 is needed at outlet port 452.

Conversely, in the event that the pressure of the coating material 48 being applied to head assembly 16 is too low, the variable-duty-cycle control signal (e.g., control signal 456) may be adjusted to regulate the pressure of coating material 48 being applied to head assembly 16 upward. For example, the variable duty cycle control signal (e.g., control signal 456) may be adjusted to have an increased duty cycle (e.g., control signal 456A) when an increased quantity of coating material 48 is needed at outlet port 504.

Accordingly, selectively energizing and deenergizing the one or more valve assemblies (e.g., valve assemblies 458) based, at least in part, upon the variable-duty-cycle control signal (e.g., control signal 456) may enable precise control of the quantity of coating material 48 provided to outlet port 452.

Multiple Robots

As discussed above, automated construction robot system 10 may include computational system 32 configured to execute automated construction robot process 34 and enable the interfacing with (and controlling of) one or more of mobile base assembly 12, head assembly 16, arm assembly 20, wrist assembly 22, rotation assembly 24 and machine vision system 26.

Further and as discussed above, automated construction robot system 10 may include machine vision system 26 configured to scan a target area (e.g., target area 28) and generate target area information 30. Additionally, machine vision system 26 may be configured to scan a non-target area (e.g., non-target area 72 and/or non-target area 74) and generate non-target area information 76.

While the scanning of target area 28 and non-target area 72, 74 is discussed above as being accomplished via a single automated construction robot system, this is for illustrative purposes only and is not intended to be a limitation of this disclosure, as other configurations are possible and are considered to be within the scope of this disclosure. For example, automated construction robot system 10 may include a plurality of automated construction robots, namely a primary construction robot (e.g., automated construction robot system 10); and a scout construction robot (e.g., scanning robot system 80). In such a configuration, the scout construction robot (e.g., scanning robot system 80) may be configured to effectuate the above-described scanning functionality (e.g., the scanning of target area 28 and/or non-target area 72, 74) to generate target area information 30 and/or non-target area information 76.

As discussed above, automated construction robot system 10 may be configured to be wirelessly coupled to access point 44 via wireless communication channel 46 established between automated construction robot system 10 and access point 44. Additionally, scout construction robot (e.g., scanning robot system 80) may be configured to be wirelessly coupled to access point 44 via a wireless communication channel established between scanning robot system 80 and access point 44. Accordingly, network 40 and access point 44 may be configured to allow automated construction robot system 10 and scanning robot system 80 to communicate, thus enabling the above-described scanning operations.
